when uploading: org.openstreetmap.josm.data.osm.DataIntegrityProblemException: Primitive cannot be modified in read-only dataset

[aseerel4c26]

What steps will reproduce the problem?

(not sure if that will always happen - but this is what I did:

0. could be (I do not remember if it was in this JOSM session) that I tried to open a saved data layer, forbid uploading, downloaded OSM data into it. ... tried to test ticket 8039 .
1. make some edits which involved a way split (which is part of several route relations) and changing the way's tags
2. upload

What is the expected result?

upload succeeds

What happens instead?

upload is partially done. Changeset is not closed ( ​https://www.openstreetmap.org/changeset/56471159 ) by JOSM. Apparently the data was uploaded correctly, though. When removing this data layer, JOSM warns that the layer has not yet been uploaded.

Please provide any additional information below. Attach a screenshot if possible.

In 13440/josm:

fix #15969 - upload broken (regression from r13434)

[Don-vip]

New latest version should be available in 10 minutes.

Replying to Don-vip:
awesome, thank you! :-)

With version 13440 a upload worked without problems.
